Heavy metal contamination and remediation in deep drilling across Chinese energy basins.
Review in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Deep and ultra-deep drilling in China's energy basins generates drilling fluids, cuttings, and produced water that can mobilize potentially toxic elements into soils, sediments, and aquifers. This review summarizes evidence from the Xinjiang Tarim Basin, Sichuan Basin, and Bohai Bay region on contaminant sources, release and transport pathways, ecological and human exposure, and management options. Cadmium (Cd), arsenic (As), lead (Pb), chromium (Cr), nickel (Ni), vanadium (V), (zinc) Zn, and Barium (Ba) are commonly reported in drilling-related wastes and affected media, but mobility depends on speciation, pH, redox conditions, soil properties, and hydrogeology. Prevention through lower-toxicity drilling fluids, closed-loop waste handling, well integrity, and source containment should be prioritized. Stabilization, soil washing, membrane and electrochemical treatment, phytoremediation, and bioremediation require site-specific selection. Standardized monitoring, speciation data, field validation, and direct links between engineering controls and risk reduction are needed to support safer drilling and evidence-based regulation.
